PUMP WITH DISK-SHAPED CAVITY Russian patent published in 2014 - IPC F04B43/04 

FIELD: engines and pumps.

SUBSTANCE: invention relates to pump building industry. Pump operation is based on acoustic resonance. A pump contains a housing of a cylindrical form restricting the cavity for fluid medium formed by side wall closed from both butt ends by end walls. In addition the pump contains an actuator connected to at least one end wall. It induces vibration of the end wall put in motion to generate displacement vibrations of the end wall put in motion in the cavity. Also the pump contains an insulator connected to periphery part of the end wall put in motion to reduce displacement oscillations descent. The pump contains a valve used for fluid medium flow control. The valve includes the first and the second side plates with holes displaced from each other and a side wall located between the plates embracing them along the perimeter thus forming a cavity connected to the holes by the fluid medium. The valve also contains a diaphragm located with possibility of movement between the first and the second plates and provided with holes displaced relative to the holes of one plate and aligned with holes of the other plate. The diaphragm moves between two plates induced by change of valve fluid medium pressure differential direction change.

EFFECT: pump allows generating high amplitudes waves.
